Q: Could you please tell me how to change the time.
I would be very grateful.
A: Please see pages 16 and 17 of the manual (downloads tab).
Q: I currently have this controller installed on my boiler. The numbers (temperature figures) are starting to disappear, what do I do. If I need to replace the unit can I just replace the display box on the wall or do I have to also change the box attached to the boiler.
A: Try changing the batteries. If that doesn't help, then you will probably need to change it.
Although they are only sold as pairs, you can set the new controller to work with your existing receiver.
Q: Can you please tell me how to do a reset...we have inherited one with settings all over the place ..its so complicated to reprogramme ...its beaten us after 2 days of trying
A: There is a reset button on the bottom left. You will need a pin or similar to press it.
Q: Is it possible to programme both a START and a FINISH time for each day?
A: You programme temperatures instead of on and offs, so you could programme (for example) 20C in the morning and 5C in the evening.
Q: Hi if it's not possible to turn this ch programmer off (off mode) how do I turn it off in summer?
A: You use the frost protection mode in the Summer.
Q: the last tennants have disposed the instructions !and i dont know how to use it
A: You can download it from the downloads tab.
Q: Is there a way to completely disable the programmes on this thing? Mine has several times set from previous owners all I can do is edit the programmes but want to turn it off and use it just when I want to by setting the temperature. Thanks.
A: I'm afraid it doesn't have a manual mode.
Is it possible to use 2 thermostat on 1 receiver?
Also, could you kindly please point me to where I can download these instructions to attach an additional thermostat as my plumber/installer has disposed of the manuals etc.
A: I'm afraid not. The receiver will listen to only one thermostat. You will need to install a second receiver.
Q: I have this product but the wireless controller is broken, if I get a replacement controller will it sync automatically?
A: You will need to change the address code switches on the new one to match the old one. They will then work together.
Details are included in the installation manual.
Q: I have an existing HRFS1 programmable room stat controlling my heating but I am hoping I can add another receiver paired to my existing thermostat to control some underfloor heating as well, would 1 thermostat control 2 receivers? And if so can I buy an additional HRFS1 receiver?
A: It will control multiple receivers, but they are not available separately.
Q: Can this be used on a boiler with a hot water tank?
A: As long as there is 2 x 2-Port or 1 x 3-Port motorised valves.
This will not control hot water, a separate control is needed for hot water.
Q: Is this stable to control a 2.75 kw electric radiator?
A: Yes it is.
Q: Can two separate stats be used within the same building to control two separate zones within the building
A: Yes they can.
Q: Good morning,
I have a Horstmann RF programmable room thermostat with the number inside the receiver T50. could you please tell me if the HRFS1 ( which looks the same ) is the replacement and I do not have to change the wiring inside the receiver.
Many thanks for your time
A: I'm afraid that is not the model number. Please email us a photo to firstname.lastname@example.org and we will identify it.
Q: Hi, can the controller be purchased on it's own?
A: I'm afraid not.
Can the receiver be purchased on its own?
A: I'm afraid it is only available as a pair.
